I have a few questions that I hope you guys could help with:
 

I'm currently hitting 23,367 in timespy. My GPU is hitting 175w but my CPU is maxing at around 115w. The liquid cooler means I have headroom to push more watts to the CPU and/or the GPU but my BIOS (currently running the XMG NEO 17 BIOS) is limited in it's functionality. The 13900HX is unlocked and overclockable by Intel's design but all of the available BIOSes are locked down. How do I get around this?

 

I only have a single power option in windows and that is Balanced, I've tried all of the online suggestions for having the additional power plans but not have worked. Is the High and Ultimate power plans blocked in the BIOS? Can I get around this too?

 

Historically I would have used a PremaMod BIOS but PCSpecialist is not a Prema Partner so I don't have that option, are there alternatives?

I welcome all suggestions.

Thanks.
